Fig. 5 is a viewsiinilar to Fig. 3 showi ing'the binding-of the spring'andnose-guard to indicate corresponding arm against the screw.

' Similar numerals ofreference are employed parts throughout the several'figures of the drawings.

The bow or spring 10 is of the usual shape, 5-

-, or" tapered, as-indlcated at 11, at the point with the exception that one edge is beveled wherethe. ends of the spring enter the boxes 12 of the lens-attaching studs 13. Each nose-guard is provided with the'usual supporting-arm 14:, and. the edge of the upper portionol this armdsalso beveled, as indie citizen-entitle United States, residing at Somtheir the opposite side wa l at the beveled surfaces of the and spring being opposed toeachother and forming airecessjthat is: an tionf and isarrangedfor. t we'dging-pin 17, which may other form'in cross-seetiomf Th st d' 13 isof. any ordinary construeti'onand is shown-in the present instance as provided with'a box 12 atlts inner end. One of the side walls'ofthe, box is rovided with" notches 18 for theireception 0 the bent end portions 19 ofthe wed ing'me'mber 17 ,and;

notches/or recessesin such manneri'as to pre 17o,

vent accidental disengagement'of the wed" ing member, whileg permitting considerab e lateral play thereof. The outer wall'of 'the boigis provided with an opening20 of a di-'- ameter greater thanthat of'the'head ofgthe securing screw' 21, said screw passing, 'as,-, usual, through alining openings'in the noses these ;ends are turne guard arm and spring and entering a third? opening formed. in the stud;

In assembling the spring is inserted in t e box will rest-against the inner face of the We member 17," while the nose guard arm serted in such position that the inclined ed e 15 will rest against the outer face of said"; When "the screw is in serted and turned home, the nose-guard arm and spring are forced tightly to ether, and I e Wedging 7 same outj" ,ward' against'the side Wall .of the box 12. This results in the lateral movement of the; nose-guardarm ands ring in the direction-of llof the box, and the parts-will thus be rigidl held from'independ wedging member.

eveled edges will act on t member and tend to thrust the ent movement in any irec'tion.

, While the inclosed or boX-like-construction shown in Figs. 2 and 3 is preferred on account of the resistance offered to spreaging of the side wallsor flanges, it is obvious that, th I 1 sidewalls alone maybe used, a l rly shown in Fig.4.

-. In some cases'the edges the'spring and nose gu'ard arm may not move against the side wall of the-box, but may be'driven forcip bly against one side of the screw in the manner shown in Fig. 5, so that they then act as-a p means for locking-the screw frorn turnlng movement and prevent lOOSBHIDg, of the same during the handling of the glasses.

- It isobvious that the wedging members' lar in cross-sece I'eGGPtlOILOffl be clrcular or: of

. artsltheend f of'the iii-such man ner'that the tapering edge 11 of jthe spring may be employed on both sides of the frame, if desired.

- is claime The construction of the frame forming the subject of the present invention is simple, and the cost of roduction is but little, if any, greater than 'tl iat of the .frame of ordinary construction. 1

In aneyeglass-frame, a spring, a nose- -guar d arm, a stud arranged to receive the s ring and arm, a securing-screw extendin t ough the springand arm and into sai stud, and a wedging member that is locked by the screw between the spring, the arm and the stud.
